6 Claims.

The present invention relates to dredging cans and has particularreference to a fully sealed can which is opened by breaking out ofscored parts, such a can being provided with a sliding member of simpleconstruction and one which is retained in a unique manner on the end ofthe can so that it functions selectively to close v the can after it hasbeen opened or to expose certain of its openings for dispensingpurposes. An object of the invention is the provision of a sealeddredging can which is provided with a sliding member retained in slidingcondition within the seat or panel of an imperforate can end that isperforated to open the can, the retaining means being flattened beadsstruck out as integral parts of the can end wall which hold the slideagainst displacement and at the same time allow for its freemanipulation to cover and uncover the perforations.

Anotherjobject of the invention is the provision of a sealed rectangulardredging can having a sliding member which is movable back and forwardto cover and uncover pouring and sifter openings which are made in awall of .the can when it is opened, the can wall being provided withopposed beads for guiding the slide in its movement, flattened sectionsof the beadsbeing used to retain the slide in operative condition.

Another object of the invention is the provlsion of a dredging can ofthecharacter described wherein the sliding member is provided'with 1ocatingmeans for accurately positioning it for closing of both pouring andsifting openings or for selectively uncovering either of them.

A further object of the invention is the provision of a round sealeddredging can having an imperforate end formed with a circular sunkenpanel or seat outlined by a peripheral bead or rim for the reception ofa rotatable slide member, the latter being retained against displacementby flattened sections of the circular bead which overhang the peripheraledge of the slide, the position of the slide member within its seatdetermining the type of dispensing action'for the can contents,afteropening of the can by perforating its end, or effecting a closurefor all. of the openings in the can end wall.

Numerous other objects and advantages of the invention will be apparentas it is better understood from the following description, which, takenin. connection with the accompanying drawing, discloses a preferredembodiment thereof.

Referring to the drawing:

Figure 1 is a perspective view of a rectangular dredging can embodyingthe present invention;

Fig. 2 is atop plan view of the same;

Fig. 3 is a plan view of a round can embodying the present invention;.

Figs. 4 and 5 are longitudinal sectional views 5 taken substantiallyalong the line 4-4 in Fig. 2, Fig. 4 illustrating the .can prior to itsopening and Fig. 5 showing the same after opening; and

Figs. 6 and '7 are transverse sectional views taken respectively alongthe lines 6--6 and 'l| 10 in Fig. 2.

The present invention is concerned with a dredging can having a slidingclosure member and Figs. 1, 2, 4 to '7 inclusive illustrate theinvention as it is applied to a rectangular can while Fig. 3 illustratesthe application to a round can,

Considering first the rectangular form of can the drawing illustrates arectangular body ll preferably formed of metal provided with animperforate bottom or end member l2 and an imperforate metal top endmember l3. The member l3 may be secured to the upper end of the body IIin the usual double seam M.

The top end I 3 of the can is of the usual sunken panel or dished formrequired for double seaming with a surrounding panel wall l5 which is atright angles to a web wall l6. A'second sunken panel I1 is formed in theend panel wall l6 and its outer edges are substantially parallel to theboundary Wall l5. On two opposite sides of this panel within a panel,the web wall I6 is beaded as at l8 (Figs. 2 and '7) to provide a pair ofopposed beaded rims.

The bottom part of the panel I1 is flat and this section- (designated bythe numeral 2|) is partially cut through in score lines 22. The metalwithin the score lines is adapted to be pushed down and inside of thecan as an incident to opening the can and a pouring opening 23 andsifter openings 24 are thereupon formed as best 40 illustrated in Fig.5.

A metal slide member 3| is provided for sliding engagement with the flatpanel wall 2| and is located within the panel II. It has its oppositeedges in sliding engagement between the upstande ing bead rims l8 formedin the can end wall. At intervals the bead rims are flattened to provideretaining lugs 32 which extend in and overhang the longitudinal edges ofthe slide member. These retaining lugs hold the slide member againstdisplacement from its panel seat and at the same time allow for a freealthough restricted I longitudinal movement.

The two ends of the'slide member 3| are curled to provide finger pieces35 and these permit easy manipulation of the slide back and forth withinits panel seat. Prior to opening of the can the slide has no utility, asthe imperforate top before perforation acts in its capacity to seal thecontents. After the openings 23, 24 are formed the slide functions inaccordance-with its position within its panel seat.

When the slide member 3| is in its central posit-ion both the pouringopening 23 and the sifter openings 24 are covered and in this positionthe slide acts as a. closure for the can. When the slide member is movedtoward the right (Figs. 1, 2 and 5) the sifter openings 24 are uncoveredand a sitting of the contents may be had through the sifter openings.When the slide member is in the opposite end of its, seat, the sifteropenings 24 are covered but the pouring opening 23 is uncovered. The cancontents may then be dispensed through the latter.

The flat slide 3| may be reinforced by an oblong bead 36 which is struckup from the met-al and a central button 31 is also preferably pressed inthe metal of the slide just inside of the oblong bead. This bead 36 inaddition to strengthening the slide is utilized, as is also the button31, in a locating stop capacity as will now be further explained.

The fiat wall 2i of the recessed can top is pressed up at its centerinto a button 38, best illustrated in Fig. 4. This 'button cooperates selectively with the two ends of the oblong bead 36 or with the button 31in locating the slide in one of its three positions. The button 31 ofthe slide engages with the can end button 38 when the slide is in itscentral or can closing position, In the other two positions of theslide, the button 38 snaps into one or the other ends of the bead 36 andin like manner definitely locates the slide in its pouring or siftingpositions.

In the adaptation of the instant invention to a round can, the circularend (designated by the numeral, Fig. 3) is formed with a circulardepression or panel 42 which in this form is preferably surrounded witha circular bead rim 43. A rotatable slide member 44 is herein providedand is located inside of the surrounding bead rim 43. This beaded rim isflattened at spaced intervals' as at 45 to provide retaining lugs whichoverhang the periphery of the rotatable slide 44 and keep it in its seatwhile permitting free rotation.

The wall of the end inside of the sunken panel 42 is partially cutthrough in an oblong or kidney shaped score line 46 and inseveralcircular score lines 41. The sc res are broken through and the metal ofthe end inside of the score lines is pushed into the .can in the samemanner as before when the can'is opened. This displacing of the metalprovides a pouring opening 48 and sifter openings 49.

The rotatable slide 44 is also formed with a kidney shaped opening 5|and when this is brought into register with the pouring opening the cancontents may be dispensed therethrough. In like manner a registrationwith the sifter openings 49 permits sifting of the can contents. Whenthe slide opening 5| is out of register with either the pouring or thesifter openings the slide functions as a closure for the opened can. Afinger piece 52 struck up from the slide wall or attached theretoprovides for easy manipulation of the slide to rotate it into itsseveral positions.

It is thought that the invention and many of its attendant advantageswill be understood from the foregoing description, and it will beapparent -lined by score lines cut in said panel wall, the

metal within the score lines being adapted to be pressed inside of thecontainer to open the same,

a slide member located inside of said sunken panel and having athickness substantially equal to the depth of the latter, said slidemember having an edge adjacent said beaded rim, the latter beingflattened at spaced intervals to provide retaining lugs which projectover said slide edge and slidably retain the slide in its seat so thatit is movable into different positions to cover both pouring and sifteropenings or to selectively cover only one of said openings.
